She ignored the jest. “If it was Father who’d been taken captive, Jaime would not be sitting by idly, I promise you.”Jaime would be battering his host to bloody bits against the walls of Riverrun, and the Others take their chances. He never did have any patience, no more than you, sweet sister. “Not all of us can be as bold as Jaime, but there are other ways to win wars. Harrenhal is strong and well situated.”

It's a grand irony how in the end Jaime is the one that comes with the plan how to take Riverrun without storming it.

"Tyrion watched the faces of the Lords Tyrell, Redwyne, and Rowan, wondering if any of the three would be bold enough to say, 'But Lord Tywin, wasn't it you who presented the bodies to Robert, all wrapped up in Lannister cloaks?' None of them did, but it was there on their faces all the same. Redwyne does not give a fig, he thought, but Rowan looks fit to gag." House Redwyne is one of the houses Viserys lists as a Targaryen loyalists, but I think the quote foreshadows that they won't be when Targaryen claimants pop up in Westeros. On the flipside, I think House Rowan will either support Dany or be one of those "friends in the Reach" that support Aegon.

I think tze or someone wrote some foreshadowing about dany having trouble with the Redwynes so your probably right, i think it's in the learning to lead threads though

Mathis Rowan is currently commanding the Siege of Storm's End.

He [Septon Meribald] had a seamed, windburnt face, a shock of thick grey hair, wrinkles at the corners of his eyes. Though a big man, six feet tall, he had a way of hunching forwardas he walkedthat made him seem much shorter. His hands were large and leathery, with red knuckles and dirt beneath the nails, and he had the biggest feet that Brienne had ever seen, bareand black and hard as horn.

This may be reaching, but the colors associated with Meribald are the colors of House Targaryen and House Stark.

Meribald: "my soles would bleed like pigs whenever I trod on hard stone"

Trying to get through all the previous threads, but have only managed v1 so far, so perhaps this one I noticed in my AGoT reread has been mentioned:
Ned's POV during confrontation with Jaime over Cat's seizure of Tyrion, Jaime says "would the noble Catelyn Tully murder an innocent hostage?" I believe Jingle Bell would have to answer YES.

Nice one... Not only had I not caught that, it's one I've never seen posted before. Well done :-)

Not exactly foreshadowing but it has come up before that Varys killing Kevan with a crossbow may link the murder to Tyrion. Cersei tells Jaime:

“Safe.” The word tasted bitter on her tongue. Jaime did not understand. No one understood. Only Melara had been in the tent to hear the old hag’s croaking threats, and Melara was long dead. “Tyrion will not kill the same way twice. He is too cunning for that. He could be under the floor even now, listening to every word we say and making plans to open Tommen’s throat.”

It could be Valonqar irony too-- Joffrey was killed by the strangler (the poison) and the valonquar will strangle Cersei neither of which will be done by Tyrion.

Sansa forshadows Jon Snow taking off Janos Slynt's head in A Game of Thrones (Pg. 746):

Frog faced Lord Slynt sat at the end of the council table wearing a black velvet doublet and a shiny cloth-of-gold cape, nodding with approval every time the king pronounced a sentence. Sansa stared hard at his ugly face, remembering how he had thrown down her father for Ser Ilyn to behead, wishing she could hurt him, wishing that some hero would throw him down and cut off his head.

Sandor calling Sansa little bird is a foreshadowing to her role as Littlefingers bastard. And possibly a marriage to Robert Arryn, with the Mockingbird and Falcon sigils respectively.

I also think it's a nod to her budding political espionage (like Varys' spies are also called little birds) and maybe even a clue as to how her skinchanging ability will eventually manifest (she'll skinchange into birds).
